Step-wise induction, amplification and inversion of molecular chirality through the coordination of chiral diamines with Zn(ii) bisporphyrin

A clear structural rationalization of the origin of chirality transfer from an optically active diamine guest to an achiral Zn(ii) bisporphyrin host in a 1 : 1 and 2 : 3 host–guest supramolecular complex has been demonstrated for the first time. During the process, chirality inversion along with amplification was observed.
